There are provided orthopedic casts, splints, and the like, for use on a portion of a human or animal body, which are produced from a crosslinked copolymer of a lactone monomer and a polyfunctional acrylate monomer. The crosslinked copolymer, in the form of a sheet, web, bandage, etc., and, optionally, a supportive substrate, is heated above the softening point of the copolymer, manipulated to conform to the body portion, and cooled to a rigid state.
In one embodiment, there is provided a bandage material, convertible to a rigid, porous, light-weight orthopedic cast, which comprises a substrate in the form of a netting, having on the surfaces of its strands a coating of the aforementioned crosslinked copolymer. The bandage material is heated to a temperature at which the crosslinked copolymer is soft and self-adherent and is then wrapped around the body portion in a series of overlying layers so as to conform to the contours of the body portion. The overlying layers are fused together to form a close-fitting unitary cast and are then cooled to a rigid state.
本发明提供了用于人体或动物身体部分的矫形
石膏、夹板等,它们是由内酯单体和多官能
丙烯酸酯单体的交联共聚物制成的。交联共聚物以片状、网状、绷带等形式存在,还可选择使用支撑基材,加热至共聚物软化点以上,使其与身体部分贴合,然后冷却至刚性状态。
在一个实施方案中,提供了一种可转换为刚性、多孔、轻质矫形
石膏的绷带材料,它包括网状基材,其股线表面涂有上述交联共聚物。将绷带材料加热到交联共聚物变软并具有自粘性的温度,然后用一系列覆盖层包裹身体部分,使其符合身体部分的轮廓。覆盖层熔合在一起,形成一个紧密贴合的整体铸型,然后冷却至硬质状态。
